Be it known that I, ALBERT W. DUsEN- BERY, citizen of the United. States, residing at Ionia, in the county of Jewell and State of Kansas, have invented certain new and useful Improve/ments in Drait-Eveners, of which the following is a specification.

The present invention providesnovel means for equalizing the five horses when hitched to a cultivator or like agricultural implement to be drawn over the field with the animals abreast.

For a full description of the invention and i the merits thereof and also to acquire a knowledge of the details ot construction and the means for effecting the be had to the following description and ac-A companying drawings.

While the invention niaj` be adapted to different forms and conditions by changes in the structure and minor details Without'departing from the spirit or essential features? thereof, still the preferred embodiment is accompanying drawings, in

shownr in the which: v

Figure l is a' top plan View of an evener for a team ol" live horses when arranged to Work abreast. supporting timber, the equalizing levers attached thereto and the s\vinglet1ee connocted to the inner or equalizing levers.

'.lransversely spaced longitudinal bars' l are connected at their inner or rear ends to the cultivator or other implement. or niachine to be drawn in any accustomed' Wav and correspond to thills or shafts between which a single draft anim al is hitched. so as to properly direct the implement or machine in lts moveinent'over the held or road.

bars, thills or shafts l have a rod or bar 2 and a timber connected thereto in any suitable 'wa f', said arts 2 and 3 having a transverse an a para lel arrangement. The rod or bar 2 is located. in the roar ol' the timber 3 and is 1 .:onsiderably shorter than said timber and its end portions are connected by means oi' links 4 therewith. The rod or bar 2 may be draft of a team' of result, reference is to i Fig. 2 is a detail view'oi the opposing ends ot said t The part 3 is preferably of and their outer ends or arms are materially shorter than the inner arms, the ratio depend- 5 ingr upon the power to be applied to opposite I ends ot said levers to effect equalization of the draft. A iiexible connection 7 unites the inner ends of the equalizing levers and consists preferably ot' a short chain. A swinglevtree 8 provided With a sheal" pulley 9 is supported in the bite of the flexible connection 7 by means of said sheaf pulley, thereby admitting of the inner ends of the equalizing levers having a limited relative play incident to the .jogging movement ot' the team when drawing the implement or machine over t-he field. A l vdouble-tree 10 is connected to the outer arm of each cqualizin'g lever and is provided at its ends with swingle-trees 11. As shown in Fig. 1 the sWingle-tree 8 oceilpies a central position and is arranged between the draft bars, thills or shafts l Whereas the sWingle-trees l1 are located exterior to said draft bars or thills, the several sWingle-trees being in horizontal line to enable the draft animals to be arranged abreast. It is observed that the middle horse sustains the draft of the other tour horses, y two eXortin(r a pulling force upon the outer l extremity o the short arm of each equalizing lever. lt will thus be understood that by reason of the advantage of the long leverage, 4 the horse hitched'to the sWingle-tree 8 is enabled to pull his proportionate amount ot' the load. The flexible connection between the z inner ends of the equalizing levers enables i such levers to have independent movement, which, as is Well known, is connnon When utilizing arcani to pull a load. l'laving thus described is claimed as new is:

In a draft evener, the combination ol transversely spaced longitudinal bars, a timber eX- tended across said bars and connected thereto, a bar paralleling and spaced from said l timber and siniilarly connected to said longi- 't-udinal bars and having its extremities terthe invention, what Q smeer' minating a, distance from the extremities of .neeted tothe extremities ofthe short rms of 10 the seid timber end connected at its extremiseid equalizing levers and provided with pairs ties thereto,I equelizing levers pivoted *tov the of sWingle-trees. extremities of the said timber to provide In testimony whereof l aix my signature short and long arms, the letter extending inin presence of two Witnesses.
